DOI: 10.1002/hbm.24512
Abstract: The execution of coordinated hand movements requires complex interactions between premotor and primary motor areas in the two hemispheres. The supplementary motor area (SMA) is involved in movement preparation and bimanual coordination. How the SMA… read more here.

DOI: 10.1016/j.clinph.2020.11.012
Abstract: Highlights • Higher the fatigue, lesser the inhibition in movement preparation in stroke survivors.• Higher the fatigue, lesser the pre-movement facilitation and slower the reaction times.• Poor excitability modulation supports sensory attenuation model of fatigue. read more here.

DOI: 10.1093/cercor/bhz283
Abstract: In reaction time (RT) tasks corticospinal excitability (CSE) rises just prior to movement. This is preceded by a paradoxical reduction in CSE, when the time of the imperative ("GO") stimulus is relatively predictable. Because RT… read more here.

DOI: 10.1101/2022.02.19.481140
Abstract: The primary motor cortex has been shown to coordinate movement preparation and execution through computations in approximately orthogonal subspaces. The underlying network mechanisms, and the roles played by external and recurrent connectivity, are central open… read more here.

DOI: 10.3389/fneur.2018.00822
Abstract: This study applied a comprehensive electroencephalography (EEG) analysis for movement-related cortical potentials (MRCPs) and event-related desynchronization (ERD) in order to understand movement-related brain activity changes during movement preparation and execution stage of unilateral wrist extension.… read more here.
